Effects of nonylphenol on expression levels of GnRH-like polypeptide in Cipangopaludina chinensis

摘要

Nonylphenol plays the role of estrogen in influencing male organisms in water much higher than the female biological. It is typical endocrine disruptors and does harm to biological reproductive system. Gonadotropin-releasing hormone (GnRH) is a sex hormone-containing nerve decape-ptide. The main physiological role is associated with pituitary gonadotropin secretion cells specifically bind to receptors to promote cell gonadotropin secretion. In this experiment, Cipangopaludina chinensis was as experimental subjects to detect and observe the trend of nonylphenol on ovary, brain sections, and the visceral ganglion and foot ganglion GnRH-like Peptide expression in C. chinensis which lined in bottom sediments. Then, it was discussed on the toxic effects of nonylphenol on C. chinensis in bottom sediments and provides some reasonable suggestions to address the environmental impact of hormones on aquatic organisms.
